Answer:

r = 1

Step-by-step explanation:

<u>Use the slope formula:</u>

m = (y₂ - y₁)/(x₂ - x₁)
m = -3, x₁ = 4, y₁ = r, x₂ = 8, y₂ = -11

<u>Substitute values and solve for r:</u>

-3 = (-11 - r)/(8 - 4)
-3 = -(11 + r)/4
11 + r = 12
r = 12 - 11
r = 1

lauren planted 20 flowers, but her neighbors dog ate 7 of them. what percent of the flowers did the dog eat

LuckyWell [14K]

35 percent got eaten.

To solve: you’d take the number of flowers eaten, 7. And you’d divide it by the overall number, 20. Then you’d get 0.35, which would be your percent.

Consider a circle whose size can vary. The circumference of the circle is always 2 π 2π times as large as its radius. Let r r re

Alenkasestr [34]

Answer: $C=2\pi r$

Step-by-step explanation:

Let be "C" the circumference of the circle (in feet) and "r" the radius of the circle (in feet).

Based on the information provided in the problem, you know that the circumference of the circle is always $2\pi$ as large as its radius.

Notice that this indicates a multiplication. Then, this means that the circumference of the circle is always equal to $2\pi$ by "r".

Based on this, you can write the following formula that expresses the circumference "C" in terms of the radius "r":

$C=2\pi r$
